LSV was an air force (Luftwaffe) sports club that was active from 1941 to 1944 and was made up primarily of flak soldiers.
During World War II it was common in Germany for military sides to take part in domestic competition.
[1] LSV Danzig won a promotion round playoff at the end of the 1941–42 season to advance to the first division Gauliga Danzig-Westpreußen where they captured the title in 1944.
That earned the club a place in the opening round of the national playoffs where they played Hertha BSC Berlin to a scoreless draw before losing the rematch 1–7.
During the war, LSV made use of the facilities of Gedania Danzig, an ethnically-Polish club that was banned for political reasons by the Nazis in 1938.
